Is 6 nights in mid-October worth a first time trip?

My two friends and I were planning to visit Iceland in September, but due to schedule conflicts we decided to move it to mid-October.

I know October is off-season, we’ll have about 10 hours of daylight, and the weather’s unpredictable and likely raining, and we’ll have a better chance to see the Northern Lights…

…But is 6 nights worth the risk that comes from October?
